The couple, both raw vegans from New Zealand, ended their journey with an extra marathon to their home in Melbourne at 5 a.m. on New Year’s Day to set the world record.

You don’t stop doing something that works

Janette Murray-Wakelin, 64, and Alan Murray, 68, rose at 4 a.m. each day and ran 366 consecutive marathons with no days off. Ms. Murray-Wakelin said she was looking forward to a break and planned to sleep in, do some gardening and spend time with her grandchildren — and then go running the next day.

“You don’t stop doing something that works,” she told Fairfax Media.

During the run, the couple skirted a cyclone, floods, a bushfire and a hail storm near Perth, during which they took a half-hour break and drank a vegetable smoothie before continuing through the heavy weather.

Ms. Murray-Wakelin missed the birth of her fifth grandchild in June, but was running in south Queensland when a motorcycle rider called out her name and revealed he was a cousin she had not seen in 45 years. He apparently said “Good to see ya” before rushing off to work.

The couple’s standard day involved eating 10 bananas, a grapefruit, and a date smoothie for breakfast, then another 10 bananas at 8 a.m., a green smoothie at 9 a.m., a fruit salad at the 19-mile mark, three oranges at the 23-mile mark, before finishing at 4 p.m. and eating an avocado, vegetable juice and a salad for dinner.

“The first few weeks we were sore, breaking ourselves in,” Mr. Murray told ABC Radio. “After that, it actually became easier every day. I really don’t think we’ve had any days when we didn’t think we could make it. But we had a few longer days through extremes of heat. We had some 44 [C] degree days going up into Canberra.”

The run is understood to have beaten the world record set in 2011 by a Belgian, Stefaan Engels, who completed 365 marathons in a year.

Ms. Murray-Wakelin and Mr. Murray were assisted by volunteers who helped with supplies and driving a support van. They used the run to raise money for charity.
